Header set Cache-Control “max-age=37440000″

Header set Cache-Control “max-age=87000″

Header set Cache-Control “max-age=300″

It is working fine except there’s no caching of the files of the text of my wordpress site. I hear such files are .php files. At first I would think I could just slip in “php|” next to the “html” and the .php text pages would be cached for 300 seconds without causing problems. But adding “php” to the the code above would also be caching xmlrpc.php. Can caching xmlrpc.php cause problems? I asked my webhost and they said the question is a programming question and not a server issue nor concern. I asked this question on a number of forums and no one wants to touch it? What’s the big secret? There’s also this php file – xmlrpc.php?rsd. If you know or can find the answer it would be a real service to programmers who reference forums. I’ve looked at the headers of webpages coded by otherwise very capable people and the caption the header tool leaves is that the page is stale – I can only assume that’s becuase they don’t know what to do about the header set cache-control on php. Is it safe to put “php” in header set cache control (with the filesmatch function)in the coding of a site that uses xmlrpc.php?

Thanks for the help Scott,

There are far too many variables to possibly troubleshoot or even offer any suggestions by what you’ve put above, and specific code questions can only be addressed by your own web host, I’m sorry.

Header set Cache-Control “max-age=87000″

Header set Cache-Control “max-age=300″

I thought I would see some change in the header for my site, but I didn’t. Is there something wrong with the code above?

I figured it out. On the Firefox web browser, for example, choose tools, options, cache, and you’ll be able to choose how much “disk space” you want the browser to use. Disk space is hard drive space. That’s why expires works becuase browsers can save information on the hard drive that it received from the server, including mod expires information.

I’m sorry but for liability purposes and common sense I’m not going to be able to give you specific .htaccess instructions here, wince there are too many variables.

I don’t know where you’re hosted, don’t know what version of Apache your server is running, I don’t know what mods might or might not be installed on your host’s Apache, and I don’t know whether or not your host even supports calls for these mods from .htaccess.

Some have default Apache installs and some have added mods, and every host is different.
You’re going to have to take each of these questions up directly with your specific web host / server support.

Header unset ETag
FileETag None

Also,

Right now the general order of my HTacess file is:
50 or so 301 redirects
Error page directions
Default Front Page stuff
Stuff about WordPress.
Where in the .htaccess file would I put this?

ExpiresActive On
ExpiresByType text/html “access plus 25 minutes”
ExpiresByType image/gif “access plus 5 years”
ExpiresByType image/jpg “access plus 5 years”

Are Expires directions worthwhile. Do web browsers save cache in the hard drive? If not what good is telling someones browser to cache something for 5 years if the cache is lost every time their computer is shut off?

Thanks Scott,

However if the ads are quite relevant to what you’re writing about, that it really shouldn’t matter. Every site is going to be different in your case, you’re just going to have to test different colors and styles.
